Equivalence Principle: Einstein vs Strong

[Andre' Quanta]

1-What is the different between the Einstein equivalence principle and the Strong equivalence principle?
2-Is it possible to formulate the Einstein equivalence principle in this way?
"For every point in space time, always exist a chart / reference frame in which the metric in that point is Minkowski and its first derivative is null"

Another good reference is Clifford Will's "The Confrontation between General Relativity and Experiment" http://relativity.livingreviews.org/Articles/lrr-2014-4/fulltext.html . The Einstein equivalence principle is given in section 2.1, and the strong equivalence principle is given in section 3.1.

This is nice too!

Yes.
